What does obtuseness mean?
Obtuseness is the quality of being obtuse, meaning slow, dull, or insufficiently perceptive. It may describe a person's limited ability to understand an idea, recognize an implication, or respond to another person's needs. The word can also suggest insensitivity, especially when someone's failure to notice an obvious problem has consequences. In professional and public discussion, it is often used to criticize institutions, governments, organizations, or individuals for failing to understand a situation that should have been apparent. Compared with dullness, obtuseness tends to emphasize a particular failure of perception rather than simple lack of interest. It is a formal word, and its use usually indicates that the speaker considers the misunderstanding significant. Related adjective forms are obtuse and, in adverb form, obtusely.

Where does obtuseness come from?
The word derives from Latin obtusus, meaning “blunted” or “dull,” from obtundere, “to blunt” or “make dull.” English borrowed the adjective obtuse in the 16th century for its mathematical sense of a blunt angle and later extended it to describe dull or slow-witted people. The noun obtuseness developed from this adjective and refers to the corresponding quality of blunted perception or understanding.
